[Moon-net] Power Divider losses..?

[Jordan]

If I am using 1" Square AL tubing and a brass tubing with the proper D/d 
dimensions, how much loss is acceptable per port in a 2m 2 port divider?
Connectors are Amphenol silvered Ns, the brass is properly centered and 
soldered, and the dimensions are to design.

Is .1 or .2dB/port acceptable...?  ie.:
Fed with -20dBm @ 144.1 , I see -23.2 dBm at each port when the opposing 
port is terminated with a 50 ohm load.

Is this a 'normal' result...?    73...Jordan....
